Solve the given inequality.
4.2x > 6.3

x > 1.5

Step-by-step explanation:

In order to solve for x, we must isolate x on one side of the inequality.

x is being multiplied by 4.2 The inverse of multiplication is division. Divide both sides of the equation by 4.2

The solution to the inequality 4.2x > 6.3 is x>1.5

Step-by-step explanation:

First lets cover our basic known information :

Average speed = (total distance covered) / (time to cover the distance)

Total distance covered = (88 km + 84 km) = 172 km

Time to cover the distance = (4 hr + 3 hr) = 7 hours

Average speed = (172 km) / (7 hours)

Solve and your answer should be ::

24.57 kilometers per hour

hope i helped, good luck!
